Important Owner Information

For owners of a 2021 Hyundai Tucson, it's crucial to understand the status of Hyundai Tucson GDS event #1383. Hyundai has stated that "The impacted vehicles related to this event will not show open on the VIN in WebDCS while this event is under suspension." This means that if your vehicle is potentially affected, its VIN will not currently appear as having an open campaign or recall in the WebDCS system.

This suspension indicates that the investigation is still ongoing, and a formal resolution or campaign has not yet been finalized or initiated. Owners should be aware that a lack of an open status on a VIN does not necessarily mean the vehicle is not part of the broader investigation.
